Abstract
The utility model relates to structure of a pump impeller, which belongs to the manufacture field of water part assemblies. An opening ring sleeve is sheathed on a suction opening of a front cover plate of the impeller. A rear cover plate of the impeller is connected with an isolating sleeve. Blades are between the front cover plate of the impeller and the rear cover plate of the impeller. A taper sleeve is positioned in the isolating sleeve. Impeller nuts are screwed and connected to the isolating sleeve and tightly press, shrink and fix the taper sleeve on a pump shaft. The utility model has the advantages that the utility model fundamentally avoids a spline structure type isolating sleeve and a spline pump shaft, ensures the reliable and fixed connection between the isolating sleeve and the pump shaft and the strength of the pump shaft, solves the problems of poor smoothness and easy swing of impellers on a pump shaft in the background art and ensures the normal operation of the whole machine; the utility model has simple stamping molds, long service life, low processing cost, convenient and simple replacement and assembly.
Description
Technical field:
The utility model relates to a kind of formation structure of water pump vane, belongs to the pump part assembly and makes the field.
Background technique:
Existing thin-walled punching press welding water pump vane, impeller is gone out spline on back shroud, and the water pump spindle that is complementary with it is the flower axis of cone, its deficiency: the one, splined shaft processing technology difficulty, processing charges height; The 2nd, influence pump shaft intensity; The 3rd, impeller stationarity on axle is poor, easily produces swing, influences the proper functioning of complete machine.
Summary of the invention:
Purpose of design: avoid the deficiency in the back of the body technology, design a kind of spacer and need not the water pump vane that spline structure, pump shaft need not spline structure and can mate mutually.
Design proposal: in order to realize above-mentioned purpose of design, the one, be designed to the screw thread structure outside the end with spacer, what match with it is impeller nut, tapered sleeve is positioned at spacer and touches mutually with the end face of impeller nut inboard, impeller nut is screwed on the spacer, when its backspin, tapered sleeve is pressed down the contracted diameter that compresses, forces tapered sleeve and diminish affixed with pump shaft tightly.Its technological scheme: water pump vane, choma cover (1) is enclosed within on the suction port of front shroud of impeller (2), back shroud of impeller (5) is connected with spacer (3), between front shroud of impeller (2) and back shroud of impeller blade (4), tapered sleeve (6) is positioned at spacer (3), and impeller nut (7) is screwed in spacer (3) and upward and with tapered sleeve (6) compresses contraction because of fixing on the pump shaft.
The utility model is compared with background technique, the one, the matching Design of spacer, impeller nut and tapered sleeve structure, spline structure formula spacer and spline pump shaft have fundamentally been avoided, not only guarantee and spacer and pump shaft between the intensity of reliable affixed and pump shaft, and solved poor, the easy deficiency that produces swing of impeller stationarity on pump shaft in the background technique, guaranteed the normal operation of complete machine; The 2nd, press tool is simple, long service life, and processing charges is low; The 3rd, replacing, easy to assembly simple.
Description of drawings:
Fig. 1 is the structural representation of water pump vane.
Fig. 2 is the plan structure schematic representation of tapered sleeve.
Fig. 3 is that the master of tapered sleeve looks the sectional structure schematic representation.
Fig. 4 is the structural representation of impeller nut.
Fig. 5 is the plan structure schematic representation of impeller nut.
Embodiment:
With reference to accompanying drawing 1～5.Water pump vane, choma cover 1 adopt punch die tool and corrosion resistant plate impact briquetting and are enclosed within on the suction port of front shroud of impeller 2, and spacer 3 adopts stainless steel casting processing moulding or adopts stainless steel machine shaping.Front shroud of impeller 2 adopts press tool and corrosion resistant plate impact briquetting, back shroud of impeller 5 adopts press tools and corrosion resistant plate impact briquetting and is connected with spacer 3, it between front shroud of impeller 2 and back shroud of impeller blade 4, tapered sleeve 6 is positioned at spacer 3, tapered sleeve 6 is an axially open 8, adopts stainless steel casting processing moulding or adopts stainless steel machine shaping.Impeller nut 7 is screwed in spacer 3 and tapered sleeve 6 is compressed contraction and is fixed on the pump shaft.
What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations are just illustrative to the utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the present utility model.
Claims (2)
1, a kind of water pump vane, choma cover (1) is enclosed within on the suction port of front shroud of impeller (2), back shroud of impeller (5) is connected with spacer (3), between front shroud of impeller (2) and back shroud of impeller blade (4), it is characterized in that: tapered sleeve (6) is positioned at spacer (3), and impeller nut (7) is screwed in spacer (3) and upward and with tapered sleeve (6) compresses contraction because of fixing on the pump shaft.
